I'll stand alone.
Maybe I'm the only person brave enough to say it, or maybe I'm the only person bizarre enough to feel this way.
I DO want WotC to fail (with some MAJOR caveats, please allow me to put in some context).
Here's the main thing. I don't feel as though they've been very "nice" to their customers, for many of the reasons that the Auldgrump mentions above. I'd like the collective behavior of WotC as a company (including communication, policies, etc) to improve. I'd like them to learn that there are better ways to conduct business, and I think the only way they'll learn that is with a negative impact on their wallets.
Here's the other thing. I don't want them to cease to exist. I don't want D&D to end. When I say I want WotC to fail, I mean I want them to have enough of a negative impact on their wallets that they learn better ways to treat customers, gaming stores, business partners, etc. I want them to "fail" in the sense that they get a wakeup call, but not so badly that people are fired, divisions shut down, etc.
Here's the last thing. As the (or a) industry leader, I want this better policy, communication, relationship forming, and HOBBY ENRICHING behavior from them because it directly affects the health of the hobby. I think that one reason why Paizo is so beloved, and has garnered such a response is because they are doing the things I wish WotC was doing.
So, in the end, what I'd like to see is WotC start acting like an industry leader that is conducive to the health of the industry or to fail and have another take their place as leader.
